For a scientific experiment, a physicist must make sure that the temperature of a metal does not get colder than -144°C or the metal will not be usable. The physicist changes the metal's temperature at a steady rate
of -8°C per hour.
Part 1 out of 3
Lett represent time in hours. Enter an inequality. Use the fact that the rate of change in temperature times
the number of hours equals the final temperature.
The inequality is
